RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jan Pazdziora (Red Hat) 2022-12-14 18:17:21 UTC 
Description of problem:

On latest RHEL 8.8. compose (RHEL-8.8.0-20221214.2), the rule accounts_password_pam_unix_remember no longer remediates, in the ospp profile.

Version-Release number of selected component (if applicable):

scap-security-guide-0.1.63-4.el8.noarch
authselect-1.2.6-1.el8.x86_64

How reproducible:

Deterministic.

Steps to Reproduce:
1. dnf install -y /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml
2. authselect select minimal --force
3. oscap xccdf eval --remediate --profile xccdf_org.ssgproject.content_profile_ospp --rule xccdf_org.ssgproject.content_rule_accounts_password_pam_unix_remember /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml

Additional info:

I see things work on RHEL 8.7 GA with the same version of scap-security-guide, and authselect-1.2.5-1.el8.x86_64.
Comment 2 Jan Pazdziora (Red Hat) 2022-12-14 18:19:28 UTC 
Checking some things on the machine after the remediation was done, on RHEL 8.7 I see

# grep remember /etc/authselect/custom/hardening/system-auth
password     requisite    pam_pwhistory.so remember=5 

and on RHEL 8.8

# grep remember /etc/authselect/custom/hardening/system-auth
password    requisite                                    pam_pwhistory.so use_authtok                           {include if "with-pwhistory"} remember=5
Comment 6 Marcus Burghardt 2023-01-04 16:46:23 UTC 
The fix is already merged in Upstream:
https://github.com/ComplianceAsCode/content/pull/9994
Comment 7 Marcus Burghardt 2023-01-10 09:29:02 UTC 
An additional patch was necessary after the rule updates. These are the two Upstream PRs which fix this BZ:
- https://github.com/ComplianceAsCode/content/pull/9994
